(54) DEVICE FOR CLEANING DOORS OF COKE OVENS

(57) The invention relates to the mechanization of heavy and labor-intensive processes in the coking industry. The purpose of the invention is to increase the efficiency of door cleaning. The device includes a frame with a guide and upper and lower

asterisks carrying traction chains, which are connected to carriage blocks that carry cleaning elements, and an actuator, which by means of traction chains reports movement along a closed path to the carriage blocks with cleaning elements. The carriage blocks consist of two extreme carriages carrying side cleaning elements and an average carriage carrying an end cleaning element, which are articulated with each other with a distance multiple of the draw chain pitch. The extreme carriages are equipped with main rollers interacting with the guide and additional rollers interacting with the additional guides which are mounted on the vertical parts of the frame and are made adjustable in the horizontal direction. The working surfaces of the rollers are made in the form of grooves interacting with the said guides. 2 hp f-ly, 3 ill.

The invention relates to auxiliary equipment of coke shops, namely to mechanical devices for cleaning doors of coke ovens from carbon deposits of graphite and resinous deposits.

The purpose of the invention is to increase the efficiency of cleaning doors.

FIG. 1 shows a device for cleaning coke oven doors, a longitudinal section; in fig. 2 - the same plan view; in fig. 3 is a section A-A in FIG. 2.

The device for cleaning coke oven doors contains a frame 1 with a guide 2 with upper sprockets 3 and lower sprockets 4, pull chains 5 mounted on said sprockets 3 and 4, and blocks of carriages uniformly mounted on the guide and connected to the draw chains 5. Carriage blocks consist of two extreme carriages 6 with side cleaning elements 7 and an average carriage 8 with face cleaning element 9. Carriages 6 and 8 are articulated with each other with a distance multiple of the pitch of the pull chains 5. Carriages are equipped with main rollers 10, tied up odeystvuyuschimi with the guide 2, and additional rollers 11, cooperating with complementary guide oo

by them 12. The latter are fixed on the vertical sections of the frame 1 by means of oltovy connections 13 and made adjustable in the horizontal direction. The working surfaces of the main 10 and additional 11 rollers are made in the form of grooves 14, covering the working surfaces of the guides 2 and 12, respectively. The device has an actuator 15 connected to the upper sprocket 3 to move the blocks of carriages with side cleaning elements 7 and end cleaning elements 9 along a closed path around the cleaned surfaces 16 and 17 of the door 18. The device for cleaning doors of coke ovens works as follows.

When the door 18 is fed into the cleaning device, the blocks of carriages 6 and 8 enclose the door to be cleaned on both sides, while the side cleaning elements 7 contact with the surface 16, and the end cleaning elements 9 - with the surface 17. Then turn on the actuator 15, which by means of traction chains 5 reports movement by blocks of carriages 6 and 8 along a closed trajectory. The blocks of the carriages 6 and 8, moving by means of the rollers 10 and 11 in the guides 2 and 12, strictly fix the position of the cleaning elements 7 and 9 with respect to the door 18 and move them around the surfaces to be cleaned 16 and 17, clearing them of coal tar and other walling After 1-2 passes of the cleaning elements 7 and 9 around the door 18, they are told the same number of passes in the opposite direction. To do this, the actuator 15 is switched to reverse movement of the blocks of carriages b and 8. Then the actuator 15 is turned off by a command device (not shown) and the blocks of the carriages 6 and 8 occupy the initial position, i.e., the average height, as shown in FIG. one.

To clean the next door of the coke oven, the cycle of the device is repeated

The proposed device for cleaning doors of coke ovens, in comparison with the known, more effectively and efficiently cleans the door surfaces from resin

nastily. This is achieved by combining the carriages into blocks, installing these blocks by means of rollers with grooves in the guides, which ensures in the process

movement of the carriage blocks clearly fixed position of the cleaning elements relative to the cleaned surfaces of the coke oven door. High-quality door cleaning increases its gas tightness, which

reduces emissions of coke oven gas to the environment and ensures its more complete utilization.
